TOALL WHOM IT MAY CONCERN;

Beit known that I, SMITH D. WACKhIAN, of Auburn, in the county of Cayuga, and State of New- York, have' invented an Improved Axle for Vehicles, 05- which the following is a full,-clear, and exact description, reference being had to the accompanying drawings, which make part of this specification, and in which- Figure 1 represents a view in perspective of my improved axle,

Figure 2 a vertical transverse section, and v Figure 3 a vertical longitudinal section through the same.

It is the object of my invention to secure a strong, light, and effective axle, to which end my improvements consist- I First, in a novel method of constructing axles for vehicles of a single plate ot metal bent into a trough-shape.

Second, in a novel'method of combining, with a trough-shaped axle, tubular bearings, formed by rounding the ends of the axle.

In order to carry out my invention, I take a plate or bar of metal, steel by preference, and bend :it in any proper well-known Jvay into a trough-shaped axle, A, arched in the middle, as shown in thedrawings, and with its open side underneath.

The bearings B for the wheels are formed on each end byvbending the ends of the trough into a tube, and welding or soldering them together. Suitable collars c and nuts dare securedon the axle in the usual way.

Blocks e may be inserted in the ends of the trough to secure additional stiffness, and oil-ducts it" may -be provided for the lubrication of the axle.

It is obvious that the'axle may be pressed into forms-0f varying outline, Without departing from thespirit of my invention, such, for'in'stance, as'the form of an ordinary carriage-axle.

What I claim as my invention, and desire to secure by Letters Patent, is

1. A trough-shaped axle for vehicles, substantially as set forth.

2. The combination, substantially as set forth, with a trough-shaped axle, of tubular bearings.

, In testimony whereof, I have hereunto subscribed my name.
